This invention comprises a novel or improved process for the productionof a liquid disinfectant composition and the product of such process,involving the use as ingredients of a eucalyptus oil or extract and asaponaceous vehicle for the eucalyptus content.

Broadly stated, the process consists in of. the process, the provisionof substitutes for certain of the ingredients and the product oftheprocess, all as hereinafter set forth and defined in the appendedclaims.

Taking as an example a process for pro ducing 10 gallons of the liquiddisinfectant, I proceed as follows, using the ingredients specified, orcertain substitutes hereinafter mentioned, in substantially theproportions stated, although these latter may be somewhat variedaccording to requirements. 7

I take 37 lbs. of oil of Eucalyptus phal- Zamlra or oil of EucalyptusAustrah'aua and add thereto 2 lbs. of oil of Eucalyptus citriodora,these ingredients being mixed with 2 lbs. of ground rosin or equivalentsuch .as oleic acid or other suitable oil such as cotton seed oil orlinseed oil and allowed to remain until the rosinjis dissolved, a periodof twenty-four hours being usually sufiicient for this purpose with themixture stirredv from time to time. To the said mixture are then added 2gallonsof an aqueous solution of an alkali such as caustic soda, forinstance a 2 solutionof 98% purity. The compositionis thoroughly mixed,say for a period of four hours, additional water being added containingforexample 1 caustic soda until the eucalyptus content reaches orapproximates -37% of the whole,

The rosin or other substitutiona'l'ingre- 'dient used and the alkalitogether produce a saponaceous mixtureiwhich const tutes a vehicle forthe eucalyptus content in which the latter remains substantially orcompletely fixed.

' Themixture is again allowed to stand for a period of say two hours,after which "it may' tested against maximum and minimum temperaturesagainst separation of the oils, such separation, if anyshould occur,being rectified by the addition of a material to correct the balance ofWater content, such as rosin soap substance.

In producingthe disinfectant it is desir able that the oils selected,should be those having the highest bacteriological values and care istaken that the whole of the prodnets of distillation from the leaf isobtained, but. any oil of the eucalyptus species can be used, the resultof the carbolic acid coefliciency varying according tov the species 79or other saponifying selected.

As eucalyptus extracts previously referred to there may be mentionedcineol, phellandreneand piperitone which are suitable for the process.

As a substitute for the two special eucalyptus species previouslyreferred to' there may be mentioned E. elaeoplzora and E.

sideroacg lon, usually mixed together and marketed by distillers inmixed condition. 39 Again the 2 lbs. of Eucalyptus citriodom previouslymentioned maybe replaced by oil of lemon grass to obtain the odourdesired. 1

It should be remarked it is an established fact that from a 37% mixtureof eucalyptus oil with rosin soap or other saponifying matter, thegreatest bacteriological value of eucalyptus oil is obtained, superioreven to mixtures having a higher percentage of such 99 oil. Hence thespecial insistence of such percentage or approximate percentage ofoil inthe present process.

What I claim as my invention and desire to secure by Letters'Patent ofvthe United States is 1. A process for the production of a disinfectantcomposition consisting in mixing an oleaginous substance of theeucalyptus species with an oleaginous ingredient until 9 solution of thelatter, and adding an aqueous alkaline solution, which, together withsaid oleaginous ingredient, forms a sapo- 'naceous' vehicle for theeucalyptus content,

untilthe latter approximates 37% of the whole;

2. Aprocess for the production of a dis infectant compositionconsisting'in an oil of the eucalyptus species with an oleaginousingredient until solution of the latter, and adding an aqueous alkalinesolution, which, together with said oleaginous ingredient, forms asaponaceous vehicle for the eucalyptus content.

3. A process for the production of a disinfectant composition consistingin mixing an oleaginous substance of the eucalyptus species with groundrosin, and allowing to stand until the rosin is dissolved, and adding anaqueous solution of caustic soda, the latter and the ground rosinforming a sapouaeeous vehicle forthe eucalyptus content, until thelatter approximates 37% of the whole. 3

4:- A process for the production of a disinfectant composition,consisting in mixing oil of Eucalyptus plzellamlm with oil of Eucalyptuscitriodo'ra and with an oleaginous ingredient until solution of thelatter, and adding an aqueous alkaline solution which, together withsaid oleaginous ingredient, forms a saponaceous vehicle for theeucalyptus oils, until the proportion of the latter approximates 37% ofthe whole.

5. A process for the production of a disinfectant composition,consisting in mixing oil of Eucalyptus phellandm and oil of oleic aciduntil solution of the rosin, and then adding an aqueous solution ofcaustic soda until the eucalyptus oils approximate 37% of the whole.

6. A process for the production of a disinfectant composition,consisting in mixing an oleaginous substance of the eucalyptus specieswith an oleaginous ingredient until solution of the latter, adding anaqueous alkaline solution which, together with said oleaginousingredient, forms a saponaceous vehicle for the eucalyptus content, andtesting the mixture against separation of the eucal -ptus content.

7. A process for the production of a disinfectant composition,consisting in mixing an oleaginous substance of the eucalyptus specieswith an oleaginous ingredient until solution of the latter, adding anaqueous alkaline solution which, together with said oleaginousingredient, forms a saponaccous vehicle for the eucalyptus content,until the latter approximates 37% of the whole, and testing the mixtureagainst separation of the eucalyptus content, such separation ifoccurring being rectified by addition of a substance adapted'to correctthe balance of Water contents.

8. A disinfectant composition comprising an oil of the eucalyptusspecies and a saponaceous vehicle for the eucalyptus including alkaliand water, with the eucalyptus content approximating 37% of the whole.Eucalyptus citrz'odom with ground rosin and 9. A disinfectantcomposition comprising an oil of the eucalyptus species, ground rosindissolved in said eucalyptus, caustic soda and water, with theeucalyptus content approximating 37% of the whole.

In witness whereof I have signed this specification. 7
